Robert Lewis Reid is high-key - luminous, open, and weighted toward light. Robert Lewis Reid builds on cool foundations: the palette favours the blue-cyan-green arc. Chroma is moderate: colours carry enough saturation to be read as colour, but the palette stops well short of garish intensity. The most saturated colour, #D2C49B, is reserved to 8.0% of the surface, where it acts as a focal punctuation. Spanning 39 units on the value axis, the palette achieves the balance between tonal flatness and fragmentation. The palette has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively. Palette 6 sits within the larger chromatic argument that Robert Lewis Reid's complete body of work advances.
